Lewisham, London
MCS certified air source heat pump installers · Free quotes · Grant options checked at survey
Gas boiler replacements need careful running-cost comparison, because the grant can reduce the air source heat pump install price but electricity and gas tariffs still matter. In Bellingham, an installer should confirm the numbers with a home survey before you commit.
Quick answer
Can I replace a gas boiler with an air source heat pump in Bellingham?
Often yes, but the quote should be based on heat loss, insulation, radiators, hot water and the current gas boiler. Eligible homes may get up to GBP 7,500 through the Boiler Upgrade Scheme.

How to compare gas and air source heat pump quotes in Bellingham
The fair comparison is the full scope of each option, including upgrade work and the assumptions behind any running-cost estimate.
Gas quote scope
Boiler, flue, controls, labour, warranty and disposal should be clear.
Air source heat pump scope
Outdoor unit, cylinder, radiators, controls, electrics and commissioning should be itemised.
Grant line
Any approved GBP 7,500 grant should be shown separately from the full installed price.
When a gas to air source heat pump switch needs caution
Some gas-heated homes need extra design work before the air source heat pump case is strong.
Low short-term budget
A like-for-like gas boiler may still have the lower initial cost.
High heat loss
Poor insulation can increase system size and radiator upgrades.
Cylinder space
Homes without a suitable hot water cylinder need a practical storage plan.
What to ask before switching from gas to an air source heat pump
Before choosing, ask installers to explain what happens to the existing gas system and controls.
Old boiler and flue
Removal, disposal and any wall repairs should be covered or excluded clearly.
Controls change
Ask how heating schedules and room temperatures will work day to day.
Electrical work
The quote should include isolator, wiring and consumer-unit requirements where needed.
Local replacement context in Bellingham
The existing heating system matters, but so does the local housing mix. Use these points to sense-check air source heat pump quotes before relying on a headline price.
49% flats
This is the largest local housing group in the Census 2021 mix, so compare quotes against your actual layout rather than a generic average.
GBP 7,595 - GBP 10,895
Typical pre-grant installation range. Your quote should confirm the system size, upgrades and final price for the specific home.
Gas boiler comparison
Ask installers to compare the air source heat pump against your current gas use, boiler age and radiator output.
What changes after the gas to air source heat pump survey
The survey should show whether the switch from gas is mostly equipment replacement or a wider heating-system upgrade.
Boiler removal
Old boiler, flue and controls work should be included or excluded clearly.
Cylinder decision
The quote should explain any hot water storage changes.
Running-cost basis
Gas tariff, electricity tariff and seasonal performance assumptions should be visible.
Common questions
Can I get quotes to replace a gas boiler in Bellingham?
Yes. You can compare MCS installer quotes for replacing a gas boiler in Bellingham, but the useful price should be based on a home survey rather than a like-for-like appliance estimate.
Will the Boiler Upgrade Scheme apply when replacing a gas boiler?
It may apply if the home, existing heating and air source heat pump installation meet the scheme rules. The installer confirms eligibility and should show any approved GBP 7,500 grant separately.
Is replacing a gas boiler usually cheaper than fitting an air source heat pump?
A simple gas boiler swap is usually cheaper upfront. The air source heat pump quote needs to show grant treatment, radiator changes, cylinder work and running-cost assumptions before the comparison is fair.
Do I need to remove my gas supply?
Usually no. Many homes keep the gas supply for other appliances or future flexibility, but the installer should explain what happens to the old boiler, flue and controls.
What gas bill information helps the quote?
Annual gas kWh, boiler age, hot water setup and rooms that feel cold help installers compare the existing system with the proposed air source heat pump.
